Hello All
I installed a couple gauges one for input and one for output using the same shunt and it works ok but today I fired up the roof air, it pulls normally 1700 watts after the compressor kicks in and runs a bit but instead it was 1200 and the dc voltage was dropping fast as reported on the digital readout on the inverter, the watts did build to about 1400 then the inverter shut down with OL light flashing. The discharge gauge showed the voltage still up around 24.5 but amps at 45 . Started checking things out and found that the flat strap part of the shunt was heating up not where the 2/0 cable ends hook up but the strap part itself and it had warmed up in just a few minutes.
Tells me the shunts are not up to par, supposed to be 100 amp rated, at most I should have been pulling 85 amps at 24 volts.
bayite DC 6.5-100V 0-100A LCD Display is the gauge and shunt I installed. Anyone else had any problems with these?
